SHADE-HOLDER.

T0 all/whom it may concern.' y Be it known that I, HARVEY HUBBELL, a

citizen rofthe UnitedStates, residingy at Bridgeport, in the county/ofFairfield and State'of Connecticut, have invented certain new and usefulImprovements. in Shade- I'Iolders, of which the following'is a full,`

clear, and exact specification. j rIhis invention relates 4toshadeholders Vwherein the rim of the shade is gripped by a contractible ringwhich is itself carried in a support Vat 'separated points of contact insuch manner as to permit expansion andV contraction of the ring forvarious diameters of shades without disengaging the ring from thesupport. Y

rIhe presentinvention has for its object to provide in combination withal screw or cam means for contracting the ring, meansfor preventingundue movement of the ring in the support or holder, without affectingits resiliency or interfering with its free con- Y traction andexpansion.

In the accompanying drawing, Figures 1,

2, 3 and 4V show various details of one form of the invention, Fig. 1being a bottom plan view, Fig. 2 a side elevation, and Figs. 3 and 4enlarged detailsof the manner of effecting the engagement between thering andthe support to prevent rotation and displacement of the ring;Figs. 5, 6, 7 and 8 yrepresent corresponding views of a modification;and Figs. 9, 10, 11 and 12 show corresponding views of anothermodification.

Referring to Figs. 1 to 4, 1 represents the support which is providedwith suitable means for attachment to a lamp fixture, andy 3 representsthe shade, reflector or other device which is to be supported. 4represents a resilient, normally7 expanding clamping ring, which iscontained when fully eX- panded withinthe bead 5 of the support 1. Thesupport, preferably at the beaded portion, is provided with slots G,through which loops or bent portions 7 of the ring project, and also theends 8, 8 of the ring. The ends 8, 8 pass through the nuts 9, 9, beingheaded to loosely engage therewith as at 10 so as to permit a slightpivotal movement of the nuts 9. 11 represents the contracting screwhaving a thumb piece 12, and provided with opposite threads so that theends of the ring are simultaneously contracted and expanded according tothe direction and rotation of the screw. The intermediate portion of thescrew is provided with a collar 15 which en- Srpecircation'of LettersPatent. Application filed August 23, 1912. Serial 116,716,572.

gages in a slot 16 formed in the shell, to hold the screw and thereby fthe ring 4 against displacement, so that even in case the ring be verytightly contracted it `will' not disengage the loops 11 from the slots6. At the same time, it is possible to avoid a considerable projectionof the loops 7, which is objectionable in the shade `holder for variousreasons. such' as clearance, liabilityof entanglement with `otherobjects, breakage,

etc. By holding the screw 11 against longitudinal displacement by meansof the collar 15 rotating in the slot 16 of the support, the ring isthereby centered and held within a predetermined position. At the sametime, by reason of the pivoted nuts 9 which extend upwardly, thescrew11'is brought-close to the'side of the support, avoiding objectionableprojections.

In Figs. 5V to 8,' the construction of the ring and support issubstantially the same, the difference in construction being in themounting of the screw. In this form, particularly in Figs. 6, 7 and 8,theends of the ring are hooked, as at 18, through perforations in thebase of the nuts 9, thel screw 11y being provided with spaced collars-19which engage with a loop 20 and carried by the support 1, the loop 20being a small strip having its ends passed through perforations v andbent under the support as at 22. An

advantage of this form of construction isk that the screw 11 isbrought'close to the side of the body 1, as seen 'from Fig. 8. only asmall portion of the screw overhanging the bead 5. It will also be seenthat the 4nuts 9, being loosely engaged with the hooks 18, havesuflicient play to prevent binding of the threads in contracting andexpanding the ring.

" In Figs. 9 to 12. the clamping ring is similarly mounted, it beingseen thatthe nuts 25 are channeled to receive the ends 26 of theclamping ring 4, the nuts being suiiciently looseV to`allow thenecessary movement to prevent bindingand, at the same time. held fagainst rotation by: small lugs or indentations 27 forced into the spacebetween the free end of the wire 4 and the bend 28. The collar 2O on thescrew 11 is carried by a slotted projecting piece 26 which is stampedout of the body on the support and bent around as shown at 27, the innersurface of the .collar 2O bearing against the bead 5, thereby holdingthe screw against displacement.

In each of the foregoing forms exemplitying the invention, it will beseen that the contractible ring', and thereby the shade, is held againstdisplacement and centered properly in the holder without liability ofaccidental disengagement with consequent release of the shade, 0r ofdisplacement.

Various modications and changes in the speciiic arrangements hereinshown may be made without departing from the scope of the invention.

Having thus described my invention, I declare that what I claim Vas newand desire to secure by Letters Patent is:

l. A shade holder comprisingja body p0rtion having' a central apertureto receive a lamp socket, aslotted flange, a contractible ring Withinsaid flange having its ends and a. plurality of intermediate portionsloosely supported in said slots, and a screw connecting' the ends ofsaid ring, said screw interlocking witlithe body portion between theends of said ring' to limit movement thereof relatively'to the bodyportion.

2. Aishade holder comprising a body pore tion having' a slotted Hangs, acontractible ring within said iiange having its ends and a plurality ofintermediate portions loosely supported in said slots, a screwconnectingl the ends of said ring, and a shoulder on the screwintermediate the ends having engagement with the body portion to preventlongitudinal displacement of the screw.

3. A shade holder comprising a body portion having' a slotted flange, acontractible ringl Within said Harige having its ends and a plurality ofintermediate portions loosely supported in said slots, nuts linked tothe respectiif'e ends of thering, and a screw engaging' said-nutsandhaving an intermediate interlocking engagement with the body portion.

in testimony whereof I aix my signature, in presence of` two witnesses.
